    Anyone know if it is safe to dive a m62 with the 404 ECU not being chipped??

    found trigger wheel to be exactly 180 out, motor runs properly now.

    yea thats my point. the cam sensor timing is off. I was told a few posts back that the cam trigger should be in front of the sensor while the crank sensor was in the large gap of the trigger wheel, which is wrong.

    so like i said the motor runs perfect without the cam sensor plugged in, hence the incorrect trigger wheel location.

    I can confirm that the cam sensor should see signature at O/T and NOT at the gap in the crank wheel.

    The basic job is rotate the m62 cam plate 180* and cut all but the lower finger off but the one you need. Bend it to fit past the cam sensor.
    Now the finger has to pass by the sensor, when the crank sensor is in the middle of the large tooth gap on the balancer. then your done. seems all crazy hitech and shit but its not. we're all over thinking it, it's simple




    Read the Thread Below

    OK I learned most of whats needed for the obd1 swap in this thread below. Seemed like pain in the ass at first but it was only cause no one said "the cam finger needs to meet the cam sensor when the crank sensor is in the big gap" ugh that took the longest time for me to figure out...
    long thread..

    good luck :blowup:

    ok, back from the dead. iv made crazy progress now that it has warmed up.

    I got the motor to turn over and cough, will not idle. so im thinking the cam trigger wheel is not in the right location. has fuel and spark i just dont think they are happening at the right time.

    can someone confirm that the cam sensor needs to see the trigger wheel at O/T OR THE LARGE GAP ON THE CRANK TRIGGER WHEEL????? i have it seeing it at the large gap....... i hear fifty fifty from different sources.

    Also installed the chain tensioner and when trying to turn the motor over it almost looks like the tensioner dosnt have enough spring to keep the chain tight.

    i know it is actuated with oil pressure to make it stiffer while the engine is running but im afraid of the chain skipping before pressure gets to the tensioner on first start up.

    am i just worrying to much? what if you lose oil pressure in the motor?? that it boom all done?

    finished tapping the crank cover for the sensor. also took a pic of my modified cam sensor wheel when the crank sensor is in the large toothed gap on the tone wheel. everything looks to be lined up properly.
